5x + 3 is larger integer
x is smaller integer
Therefore, 6x + 3 = 51
Solve for x, plug into the larger integer equation and get that answer!! Best of luck
Answer:
27
Step-by-step explanation:
9 crew members complete a job in 3 months
Number of crew members is inversely proportion to construction time :
Let :
Crew members = m
Construction time = t
m α 1 /t
m = k/t
m = 9 ; t = 3
9 = k /3
k = 27
If t = 1 (one month)
m =?
m = k/t
m = 27 / 1
Hence;
m = 27 * 1
m = 27 workers

Answer:
25%
Step-by-step explanation:
I used a proportion
18/72=×/100
Then, cross multiply
1,800=72×
Next, find the x
1,800/72=25
x=25
Answer:
-7
Step-by-step explanation:
You use the quadratic formula of
to get:
a = 1
b = 7
c = -13
then you plug that into x= (-b ± √b²-4ac)/(2a) :
x= ( -7 ± √7²- 4(1)(-13) )/(2(1))
![x=-\frac{7}{2} + \frac{\sqrt{101}}{2} \\\\x=-\frac{7}{2} - \frac{\sqrt{101}}{2}](https://tex.z-dn.net/?f=x%3D-%5Cfrac%7B7%7D%7B2%7D%20%2B%20%5Cfrac%7B%5Csqrt%7B101%7D%7D%7B2%7D%20%5C%5C%5C%5Cx%3D-%5Cfrac%7B7%7D%7B2%7D%20-%20%5Cfrac%7B%5Csqrt%7B101%7D%7D%7B2%7D)
The sum of these two x values turns out to be:
![x=-\frac{7}{2} + \frac{\sqrt{101}}{2}+( -\frac{7}{2} - \frac{\sqrt{101}}{2} )= -\frac{14}{2} = 7](https://tex.z-dn.net/?f=x%3D-%5Cfrac%7B7%7D%7B2%7D%20%2B%20%5Cfrac%7B%5Csqrt%7B101%7D%7D%7B2%7D%2B%28%20-%5Cfrac%7B7%7D%7B2%7D%20-%20%5Cfrac%7B%5Csqrt%7B101%7D%7D%7B2%7D%20%29%3D%20-%5Cfrac%7B14%7D%7B2%7D%20%3D%207)
